You have already created a configuration

If you have already created a configuration and simply want to use the sample programs foryour CPU, follow the steps outlined below:

� Copy the sample programs (container with S7 programs) of the station from the sampleproject to the CPU of your existing project. Make sure that blocks do not overlap.

� Make sure that the hardware configuration and networking and the configured connectionsare adapted according to the descriptions below.

Summary of step 1 “Creating the Project”:

You have created a STEP 7 project

– in which you can configure your system

– and in which you can create and save your user programs.



C79000–G8976–C116–03

1. Create /open your project

2. Configure and network your hardware� Which components does the system

include?

� How are the components attached tothe network?

When completed, you will have downloadedthe hardware configuration to the stations.

�

If you start with the existing sample configuration, youshould get an overview of it before you download theconfiguration to the PLC. STEP 7 provides you withconvenient methods of obtaining an overview. You cando the following:

� Display the configuration in HW Config

� Display a station overview

� Display the networking of the stations graphically withNetPro.

� Double-click the object “Ethernet(1)” in your project in the SIMATIC Manager. This opens theNetPro view for your project.

From this display, you can start all the steps required for hardware and connectionconfiguration.

As shown in the illustration,

� the connection table for the selected CPU is displayed in the lower part of the screen;

� information about the network attachment is displayed if you point to the symbol for theinterface of the node with the mouse pointer.

T I PPage 2–8 deals with the topic“Downloading”

Manual/3/

Chapter 2

For more infor-mation...



From the information relating to the network attachments, you can recognize the followingsituation:

The CP 443-1 has the configured MAC address (node). The CPU is shown with an MPIaddress. You require this MPI addresse, for example, when you want to run diagnostic functionson the CP via the MPI attachment of the CPU with NCM Ethernet Diagnostics.

If you want to modify the network address...

... you can do this in the Properties dialog of the Ethernetnode. You can display this dialog by double-clicking thenetwork node in the NetPro view. An addressmodification may, for example, be necessary when theconfigured Ethernet address is already being used inyour network by another station.

Checking the configuration in HW Config – here based on the example of theSIMATIC 400 station(1)

� Select the station or the CPU in the SIMATIC 400 station(1) in the NetPro view; then selectEdit � Open Object. You will see the hardware configuration with an overview and adetailed view.

If you want to see the configuration of one of the displayed modules in detail,

� position the cursor on the module, for example the CP 443-1 and select Edit � ObjectProperties.

Chapter2.2.4



C79000–G8976–C116–03

Adapting the configuration in HW Config

If your hardware configuration does not match the configuration required for the sample, youcan now change the entries. You could, for example, make the following changes:

� Move modules to different slots.

– The configuration of the connections is retained.

– User programs may have to be adapted to a new module address.

� Work without a simulation module

To do this, delete the simulation module in slot 5.

� Use a different CP type

– The configuration of the connections is retained.

Outputting a station overview

Use the print functions of STEP 7 to create your system documentation. You can print out thefollowing:

� Entire station

� Selected module(s)

The printout for the CP you are using then appears as shown below:



Further information about networking the station

It is easy to obtain an overview of the existing network attachment configurations using the printfunctions in NetPro.

The printout for a configured network appears as shown in the example below:



C79000–G8976–C116–03

To download the hardware configuration to the PLC...

...follow the steps outlined below:

� Connect the PG to the MPI interface of the CPU using the MPI cable.

� Set the interface on your PG/PC for the required type of attachment. Select the PG/PCinterface in the Windows control panel to match the CPs available on your PG and to matchthe bus attachment.

� Select the menu option PLC �Download...

STEP 7 then guides you through further dialog boxes to therequired result.

Summary of Step 2 “Configuring and Networking Your Hardware”:

You have now done the following:

1. Configured the S7 stations in the STEP 7 project

2. Assigned the S7 stations to the Ethernet subnet and assigned addresses

3. Downloaded the configuration to both S7 stations.

The stations are now ready for you to configure the communication connections and download the user programs.

3.1 The Task

Sending and Receiving Data

The communication task illustrated by the sample program has deliberately been kept simple.

� A controller (SIMATIC 400 station 1) processes process data.

� It communicates with a further device (SIMATIC 400 station 2), for example to delegate acontrol job. The SIMATIC 400 station 2 returns data to station 1.

The following schematic illustrates how the program functions:

SIMATIC 400 station 1

Send job data (4 bytes)

Evaluate received data

Time Time

Process data

Accept job and executeit


Send response data (4 bytes)

The jobs and responses in the example contain 4 bytes of user data.

see Catalog ST 70

1) Newer versions of the module are normally compatible in terms of functionality; You can loadthe configuration data of the sample project on your module without needing to make changes.Please read the information in the manual of the CPs on the topic of compatibility and replacingdevices!

Alternatives:

You can adapt the sample configuration to suit your own situation. Possible modifications areoutlined below:

� S7-300 instead of S7-400

Instead of S7-400 stations, you can also use S7-300 stations (for example with theCP 343-1).

The appropriate adaptations must be made in HW Config and in the user program. You mustalso use different FC types with an S7-300.

� Using a different CPU type

� Doing without simulation modules

This only requires slight modification in the user programs (no output to the simulationmodule). It is then possible to monitor communication by displaying data blocks on the PG.

� Using other input/output modules

This may mean that module addresses are changed.

� Changing the order of the modules in the rack

This may mean that module addresses are changed with certain CPU types.



Notice

If you change the module address in the configuration, you must also adapt theuser program and the configured connection.

Programming Functions (FCs) for Communication

Two functions (FCs) are available for handling communication on theISO transport connections, as follows:

� AG_SEND (FC5) This block transfers the user data from the specifieduser data area to the Ethernet CP for transmission.

� AG_RECV (FC6)This block enters the received user data in the userdata area specified in the call.

The user program in our example was written in STL notation. As an example, the parameter assignment for calling AG_SEND and AG_RECV in S7 station 1 is shown below.

STL Explanation

Setting Block Parameters Automatically

To ensure correct parameter settings for the block calls, The LAD/STL/FBD editor in STEP 7provides you with the option of accepting all the relevant parameters from the hardwareconfiguration (HW Config) and from the connection configuration automatically. When assigningthe parameter values for the block in the user program, follow the steps outlined below:

� Select the block call and its block parameters;

� Select the menu command “Connections...” with the right mouse button.

� Depending on the block type, you can now select the connection intended for the block ormodule from a list.

� Confirm your selection; as far as possible, the available parameter values are entered in theblock call.

FCs AG_LSEND/ AG_LRECV for longer data areas (CP 443–1)

The newer versions of the Ethernet CPs with the FCs AG_LSEND (FC50) and AG_LRECV cantransfer larger data areas (up to 8192 bytes). Please check the manual of your CP for thesupported data area and, if applicable, use the appropriate FCs.

Working with the FCs is explained in the manual.

Extending the Sample Program

You can also extend the sample program or later your own applications. Some possibilities areshown below:

� Evaluation of the result codes of the FCs AG_SEND and AG_RECV to allow you to react tospecific statuses in your system.

� Conditional initiation of communication calls depending on result codes, so that, for example,the send call on the client is only triggered again after the job confirmation has beenreceived with the receive call.

� Evaluate the parameters DONE, ERROR andSTATUS for AG_SEND and NDR, ERROR andSTATUS for AG_RECV. You evaluate theseparameters as shown below:

Job

Completed without error Active Terminated with error

Typical error codes that must behandled by the user program:

8302H Lack of resources on partner8311H Destination station not (yet)

obtainable (e.g. due to startup)80C3H Resources occupied (due to

maximum load on S7-400)80D2H Module start address wrong (e.g.

you forgot to change the address after moving a module)8304H Connection not yet established

DONE/NDR = 1ERROR = 0STATUS = 0

DONE/NDR = 0ERROR = 0STATUS = 8180/8181

DONE/NDR = 0ERROR = 1STATUS = x

Example without simulation module

If you do not want to use simulation modules, simply deactivate the output “T QW ...” in theFC31 blocks on Simatic 400 station 1 and 2.

You can then follow the execution of the program by displaying the data blocks online in STEP7/STL.

� Change the CPU to STOP or RUN-P.

� Select the Blocks container in the appropriate station in the SIMATIC Manager.

� Download the entire program (except for the system data) to the S7 station using the PLC�

Download menu command.

� Change the CPU to RUN-P or RUN.

� Repeat the download procedure for the other station.

Summary of Step 4 “Creating the user program”:


– Created user programs according to the task description for both SIMATIC 400 stations

– Extended the sample programs, for example by evaluating the status codes

– Downloaded the user programs to the CPUs of both SIMATIC 400 stations

Result:

If you are working with simulation modules, you should now see the active LED displays onthe simulation modules or output modules indicating that communication is taking place.

If you cannot detect any communication, do one of the following:

� Check the program sequence online in STEP 7/STL (monitor blocks). Check whether achanging data word is being output to the simulation module.

� Go on to the next step and check communication with NCM Ethernet diagnostics.

Note:In the RUN-P mode, the block or-der is important since the CPU cy-cle is active. Make sure thatOB100 is only executed duringstartup.
